I only had broccoli rice once, from asda, & loved it! But, haven't found it anywhere else! Asda stopped selling it for lack of demand! I hate cauliflower as, apparently, I'm a super taster (lots of tastebuds on the tongue) & find it very bitter! I love the metallic taste of iron in broccoli &, along with spinach, one of my favourite green iron rich vegetables! I could distinguish the lack of 2tsp less sugar in a big vat of curry sauce. I used to taste all of the sauces at our family restaurant everyday for many years as, the chefs couldn't taste that small a difference!
I've been low in iron for some time, don't know for how long, & am taking iron tablets so, can't eat too much of iron rich foods for the next few months! But, I usually eat a lot of vegetables! Was practically a vegetarian for 6 years because of a fatty liver which seems to have healed itself & only started eating meat again very recently!
